SPEQIFICATION forming part of Lettelf$ Latent N0. 531 ,903, dated January 1, 1895. Application filed April 3. 1894. Serial No. 506,140. (No model.)

To all whom it may concern.-

fication.

My invention relates to an attachment to machines for making horse shoes by which the heel ends of the shoe when being coinpressed at the sides may be held in position on the frog-formed dies; the object of my invention and improvement being to hold the shoes firmly and to prevent the metal when acted upon by the side compressors from extending outwardly from the shoe instead of laterally in line with the latter, and these results I accomplish by means of a heel-holder which is operated to descend on to the top.

surfaces of the shoes at their heel ends, while the side compressors engage with the sides of the shoe at its heel ends and compress the shoe thercat against the side of the die-frog. Accompanying this specification to form a part of it there are three plates of drawings containing seven figures illustrating my in vention with the same designation of parts by letter reference used in all of them.

Of the illustrations Figure 1 shows a part of a die wheel with its perimetral face fronting the view, a frog-form die thereon, a shoe that has been bent about the latter, and a heel compressor at each side of the die wheel thereon. Fig. 2 shows a side view of a part of the die wheel, one of the frog-form dies, a shoe that has been bent thereon, and the heel holder in contact with the latter at its heel end on its outer surface. Fig. 3 shows in an enlarged representation a section taken on the line as, 0:, of Fig. 2. Fig. 4 is a perspective of the heel holder and the frame in which it slides, shown as detached. 7 Fig. 5 is a side View of the heel holder proper detached from the frame in which it slides. Fig. 6 is a front end view of the heel holder disconnected from the mechanism which operates it, with the parts shown at Figs. 4 and 5 illustrated in larger size than in the other figures. Fig. 7

shows in a rear elevationa machine for making horse shoes with my invention applied thereto.

The several parts of the mechanism thus illustrated are designated by letter reference and the function of the parts is described as follows The letter I designates the machine frame; A, the main driving shaft operated by a pulley not shown.

The letter G designates a gear wheel on the end of the shaft A.

The letter A designates another shaft having thereon a gear wheel G which meshes into the gear wheel G, to receive power from the shaft A, and to communicate power to the shaft A This latter shaft operates the bending mechanism and the blank holder, which form no part of the invention herein described.

; The letters B, B, designate beveled gears which are arranged on the shaft A, and each of which meshes into a beveled gear B, on one of the vertical shafts A that operate the side swagers.

The letter A designates the die wheel shaft, and R a double ratchet wheel thereon, which is operated by pawls P, of which only one is shown, and by which an intermittent motion is communicated to the die wheel W, and its shaft A The letter D designates the frog-form dies mounted on the perimetral face of the die wheel. This frog-form die is made with the frog d having vertical sides (1 and restingon the fiat plate d", which subtends the die proper at the sides, to produce the ledge or shelf d and is of the usual form.

The letter C designates the heel compressors, of which there is one at each side of the wheel W, and these compressors are each made with an engaging edge 0 having a slightly curved form and they are each operated and adapted to be moved in lateral slides, so as to engage with the shoe at its heel end on the outer side thereof when the shoe is at rest, and then recede therefrom with reciprocating movement whenever the wheel is at rest. These heel compressors are each actuated by a banjo-form lever L, operated by an eccentric upon one of the shafts A, by which they are reciprocatingly actuated to engage with the heel ends of the shoe at each side when the die wheel is at rest. The function of these compressors is to give form to the heel end of the shoe.

The letter H designates the heel holder which is made with two engaging shoe faces h h that will straddle the die-frog, and these shoe engaging faces are preferably projected inwardly and extended downwardly on an angle that will fit them to engage with the exterior face of the shoe on the die, as each of the latteron the wheel W, comes to a period of rest in its intermittent revolution when opposite the holder, and the function of the latter is to engage with the outer surface of the shoe on the die, to prevent the heel compressors from thickening up the shoe thereat while elongating or shaping the heel ends.

The heel-holder H is arranged in aframe F, made with slides S, in which to be vertically reciprocated by the pitman P connecting with the holder by the knuckle joint N. This pitman P is operated to rise and fall byaconnection made with the apparatus actuating the top swagers which is not shown. This heel-holder proper connects with the sliding member M, at 10 and is made detachable thereat for the attachment of diiferent sizes of holders as suited to operate upon different sizes and kinds of shoes. The sliding member M, of the heel-holder, is made with a projection m that enters a recess m made in the holder proper and connects with the sliding member by means of a bolt and nut at each side of which one is shown at Fig. 4.

The parts thus constructed are operated as follows: The die-wheel W having arranged upon its perimeter a series of frog-form dies and actuated with alternating periods of mo tion and rest, on which during the intervening of the latter conditions, a shoe blank has been bent and top-swaged upon the dies which in approaching revolution come to a period of rest opposite the holder, the latter is actuated to descend onto the shoe, its engaging faces 7L2, k straddling the die-frog, and immediately thereafter or at the same time, the compressors C, are actuated to move inwardly to engage with the side edges of the shoe to shape its heel-ends, and then the compressors and the holder move away from their contact with the shoe to repeat the operation when another die and shoe come into position.

As the function of the heel-holder is to hold the shoe while the side compressors are operating, the form of the compressors and the heel-holder may be variously modified and still perform the same office; and its function would be the same whether a series of frogform dies were arranged upon a die-wheel actuated with alternating periods of motion and rest, or were so connectedly operated in any other manner that would bring the dies and bent shoes under the action of the holder and compressor in substantially the same manner.

In Letters Patent granted to me November 15, 1887, No. 373,125, there is a blank holder shown and described as engaging with a shoe blank while being bent around frog-form the invention shown herein, the holder descends upon the shoe after having been bent,

to hold it in position while being side swaged to give form to the heel ends.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a mechanism for compressing the heel ends of horse shoes at their sides While upon the frog form dies on which they have been bent, of a heel-holder constructed to straddle the die on which the shoe is held and on which it has been bent, operated to descend onto, and engage with the top surface of the shoe at its heel-ends, to remain in such contact while the compressor mechanism is operating, and then to recede therefrom, substantially in the manner as and for the purposes set forth.

2. In a machine for making horse-shoes, havinga series of frog-form dies that are connected and operated to move progressively with alternating periods of motion and rest, the combination with a side compressor arranged upon each side of the dies, operated to engage with the outer side surfaces of the shoes at their heel ends, where upon the sides of the dies, and where at rest thereon between said compressors; and a heel-holder constructed to straddle the dies and operated to descend upon the shoe at its heel ends, to remain in such engagement while the side compressors are operating to shape it, and then with the side compressors operated to recede from such engagement, substantially in the manner as and for the purposes set forth.

3. The combination with a series of frogform dies formed substantially as described; and arranged to be moved progressively with alternating periods of motion and rest, of a heel compressor arranged at each side of the dies and each actuated to engage with one of the outer faces of a shoe upon the latter at its heel ends at the same time when coming into position between said compressors and then to recede therefrom; of a heeLholder constructed to straddle said die, and operated to descend upon the outer face of said shoe at its heel ends, simultaneously with the inward movement of the side compressors, and then with the latter to recede therefrom, substantially in the manner as and for the purposes set forth.

Signed at the city of Troy this 7th day of July, 1893, and in. the presence of the two witnesses whose names are hereto written.
